A Laurel teenager was indicted on armed robbery and assault charges after police matched his DNA to DNA found on a Dallas Cowboys hat left at the scene of a December 2011 armed robbery of a Columbia woman inside her home.

Haanief Singley, 19, of the 7600 block of Clarissa Lane in Laurel, was indicted on armed robbery, first-degree burglary, first-degree assault, intent to injure with a dangerous weapon and theft charges last week by a Howard County grand jury.

Singley is accused of cutting a woman's face with a knife during a Dec. 2, 2011 robbery of a Harper's Choice residence, located in the 5400 block of Eliots Oak Road.

According to the charging documents, Singley was identifed as a potential suspect in June after Maryland State Police notifed Howard County Police that Singley's DNA matched the DNA of the Dallas Cowboys hat found at the scene of the crime.

The victim told police a man wearing a Cowboys hat forced his way into her home at 1:30 p.m. that day and demanded money by threatening her with a knife. The victim said the man cut her face, from the corner of her right lip to her chin area, during the incident, according to charging documents.

While the man was going through the victim's wallet, the victim said, she pulled out a knife and a struggle ensued. The victim was cut and beaten by the man, who may also have been injured, police said. The man fled, but left the hat at the scene.

A warrant for Singley's arrest was issued on Oct. 18, and Singley was detained by police six days later in Baltimore.

During an interrogation with a detective, Singley admitted to his role in the Dec. 2 armed robbery and said the incident was drug-related, according to charging documents.
